It looks like the thermometer probe I don't secure it (Thermostat probes MUST be secured) They move around some but if the thermometer is secured at either end with loose cable in between the snake can become tangled in it. A loose cable is just is pulled around. I don't like see 92º especially given the specs for the some accurites (+/-4ºF) I usually use 90º this accounts for the typical error of most thermometers (+/-2ºF) so if it is reading 90 it could be between 92-88ºF which is an acceptable range.
